Basic earnings per share amounts are calculated by dividing net profit for the year attributable to ordinary equity holders of the parent by the weighted average number of ordinary shares outstanding during the year.
Diluted earnings per share amounts are calculated by dividing the net profit attributable to ordinary equity holders of the parent adjusted for the effect of any potential share exercise by the weighted average number of ordinary shares outstanding during the year plus the weighted average number of ordinary shares that would be issued on conversion of all the dilutive potential ordinary shares into ordinary shares.
